城市轨道交通延伸线路列车编组方案研究OA

As one of the technical standards of urban rail transit,train marshalling is very important for the construction and later operation of the line.The line network in various places continues to extend to the edge of the city.The passenger flow in the central city is large,and the passenger flow in the peripheral area is small or the initial and recent passenger flow is small.Under the background of the unbalanced characteristics of time and space such as long-term passenger flow,it is urgent to study the grouping of existing extension lines.The paper first summarizes the use of urban rail transit marshalling at home and abroad,and illustrates the application trend of mixed-run marshalling and flexible marshalling.The operation plan of the 6-vehicle mixed-run marshalling is based on the evaluation indicators such as full-day,peak full load rate,all-day traction energy consumption,and vehicle purchase costs.The reconstruction cost of the platform door system,communication system,signal system,and the scale of the field section shows that after Line 6 adopts 4-vehicle and 6-vehicle mixed operation,the initial,near and long-term passenger flow service level of operation can be improved by 3 pairs/h at the same time,the full-day and peak full load rate has been improved.In terms of economy,the vehicle purchase cost can be saved by 110 million yuan,the electricity consumption can be saved by 620 million yuan,and the engineering and system transformation cost is 140 million yuan.Overall,the operation period is based on 25 years.Comprehensive cost 590 million yuan can be saved.In terms of comprehensive operation and economy,the second phase of Line 6 recommends a 4-vehicle and 6-vehicle mixed-run marshalling plan.
